ER		 27;; This package implements a major mode for editing binary files. It uses
28;; a program called hexl, supplied with the GNU Emacs distribution, that
29;; can filter a binary into an editable format or from the format back into
30;; binary. For full instructions, invoke `hexl-mode' on an empty buffer and
31;; do `M-x describe-mode'.
32;;
a2535589
JA		 33;; This may be useful in your .emacs:
34;;
35;; (autoload 'hexl-find-file "hexl"
36;; "Edit file FILENAME in hexl-mode." t)
37;;
38;; (define-key global-map "\C-c\C-h" 'hexl-find-file)
39;;
40;; NOTE: Remember to change HEXL-PROGRAM or HEXL-OPTIONS if needed.
41;;
42;; Currently hexl only supports big endian hex output with 16 bit
43;; grouping.
44;;
45;; -iso in `hexl-options' will allow iso characters to display in the
46;; ASCII region of the screen (if your emacs supports this) instead of
47;; changing them to dots.

87This function automatically converts a buffer into the hexl format
88using the function `hexlify-buffer'.
89
8a1281b5 90Each line in the buffer has an \"address\" (displayed in hexadecimal)
a2535589

92are at and 16 characters from the file (displayed as hexadecimal
93values grouped every 16 bits) and as their ASCII values.

96unprintable (control or meta characters) they will be replaced as
97periods.

120Movement is as simple as movement in a normal emacs text buffer. Most
121cursor movement bindings are the same (ie. Use \\[hexl-backward-char], \\[hexl-forward-char], \\[hexl-next-line], and \\[hexl-previous-line]
122to move the cursor left, right, down, and up).
123
124Advanced cursor movement commands (ala \\[hexl-beginning-of-line], \\[hexl-end-of-line], \\[hexl-beginning-of-buffer], and \\[hexl-end-of-buffer]) are
125also supported.
126
127There are several ways to change text in hexl mode:
128
129ASCII characters (character between space (0x20) and tilde (0x7E)) are
130bound to self-insert so you can simply type the character and it will
131insert itself (actually overstrike) into the buffer.
132
133\\[hexl-quoted-insert] followed by another keystroke allows you to insert the key even if
134it isn't bound to self-insert. An octal number can be supplied in place
135of another key to insert the octal number's ASCII representation.
136
137\\[hexl-insert-hex-char] will insert a given hexadecimal value (if it is between 0 and 0xFF)
138into the buffer at the current point.
139
140\\[hexl-insert-octal-char] will insert a given octal value (if it is between 0 and 0377)
141into the buffer at the current point.
142
143\\[hexl-insert-decimal-char] will insert a given decimal value (if it is between 0 and 255)
144into the buffer at the current point.
145
a2535589
